• and
• a main body;
• wherein the nozzle comprises a squirting tube;
• the squirting tube comprises an inlet, an outlet, and a flow channel communicating the inlet and the outlet;
• wherein the squirting tube at least comprises a first bending position and a second bending position, so as to form a main flow section, a first bending section, and a second bending section in a direction from the inlet to the outlet, the main flow section, the first bending section, and the second bending section are sequentially connected;
• the first bending section is disposed between the first bending position and the second bending position, the second bending section is disposed between the second bending position and the outlet, an extension direction of the first bending section is different from an extension direction of the main flow section, and the extension direction of the first bending section is different from an extension direction of the second bending section;
• wherein a section of the flow channel in the main flow section defines a first central axis, the outlet is located on a first side of the first central axis, the first bending section bends and extends from the main flow section to a second side of the first central axis, and the first side of the first central axis is opposite to the second side of the first central axis;
